定义
智力发育障碍是一组起源于发育期病因不同的疾病，其特点是智力功能和适应性行为明显低于平均水平，根据适当规范和个人管理的标准化测试，大约低于平均水平两个或更多的标准差（大约低于2.3百分位）。如果没有适当的规范化和标准化测试，智力发展障碍的诊断需要更多地依靠临床判断，以恰当可比行为指标评估为基础。
Disorders of intellectual development are a group of etiologically diverse conditions originating during the developmental period characterised by significantly below average intellectual functioning and adaptive behaviour that are approximately two or more standard deviations below the mean (approximately less than the 2.3rd percentile), based on appropriately normed, individually administered standardized tests. Where appropriately normed and standardized tests are not available, diagnosis of disorders of intellectual development requires greater reliance on clinical judgment based on appropriate assessment of comparable behavioural indicators.
